You would have to use this with a cronjob or something of the sort
View scrapehn.js
var casper = require('casper').create({viewportSize: {width: 960, height: 600}});
var fs = require('fs');
casper.start('https://news.ycombinator.com/', function() {
var now = this.fetchText('#hnmain');
var old = fs.read('old.txt');
if (old !== now) {
casper.open('http://text-compare.com/', {
method: 'post',
data: {'text1': old, 'text2': now}
You can’t perform that action at this time.
